    \class QVideoFrameFormat
    \brief The QVideoFrameFormat class specifies the stream format of a video presentation
    surface.
    \inmodule QtMultimedia

    \ingroup multimedia
    \ingroup multimedia_video

    A video sink presents a stream of video frames.  QVideoFrameFormat describes the type of
    the frames and determines how they should be presented.

    The core properties of a video stream required to setup a video sink are the pixel format
    given by pixelFormat(), and the frame dimensions given by frameSize().

    The region of a frame that is actually displayed on a video surface is given by the viewport().
    A stream may have a viewport less than the entire region of a frame to allow for videos smaller
    than the nearest optimal size of a video frame.  For example the width of a frame may be
    extended so that the start of each scan line is eight byte aligned.

    Other common properties are the scanLineDirection(), frameRate() and the yCrCbColorSpace().

    \value Format_YUV420P
    The frame is stored using an 8-bit per component planar YUV format with the U and V planes
    horizontally and vertically sub-sampled, i.e. the height and width of the U and V planes are
    half that of the Y plane.

    \value Format_YUV422P
    The frame is stored using an 8-bit per component planar YUV format with the U and V planes

    \value Format_IMC2
